The portable CTEL (A34/6) is connected to the Digital Data Bus (D2B) of the vehicle via the UPCI portable CTEL holder (Universal Portable CTEL Interface) (A34/15).

Voice is input via the hands-free system microphone (B25) and output via the audio loudspeaker system. The portable CTEL (A34/6) must be in the UPCI portable CTEL holder (Universal Portable CTEL Interface) (A34/15) to do this.

This displays a series of messages in the screens of the following components:

• Portable CTEL (A34/6)
